Have twice now had an issue with my SRT6 - which produces codes P0638 & 0226. Symptoms are that car drives great then revs will fluctuate up/down, car goes into limp mode. Then on restarting issue will go away.
Codes could be TPS in accelerator pedal or in Throttle body itself.
Am reaching out to see if anyone else ever had the same codes?
Am leaning towards (hoping even) is “just” a new pedal rather than throttle body?
